What this shows Sansha's Innovation Score is 44.3/100 (top 26% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Sansha?

Each dot is one of Sansha’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Sansha’s own 5.9 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sansha's grants concentrate

Sansha Electric Manufacturing Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 31.8% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2020. By volume, Sansha sits between RightQuestion, LLC and Senqcia Corporation.

Sansha's three-year grant acceleration

Sansha Electric Manufacturing Co., Ltd. shows 10 grants in 2022–2024 against only 4 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
